SpidermanPuddin on "Set Custom Query Pagination"

I have a unique situation where the query I’m using has to be a custom select query. Because of this the global $wp_query paginates. This makes some plugins and other functions add additional coding that is unnecessary.

I’ve tried several functions to fix this. Including this:

add_action( 'pre_get_posts',  'change_posts_number'  );
function change_posts_number( $query ) {
        $query->set( 'posts_per_page', -1 );
    return $query;
}

Also I'm using Genesis.
